The' chamber ot this trap opposedly to its' discharge end, isprovided Withaf transverse approximately' horizontal; nozzlel chamberforming wall l. The discharge port'of the nozzle chamber is' indicatedEby 5 and faces the discharge" end of the' trap'; The discharge endfotthe trapis' in connifiuni'cationL with a Waste transfer conduit 6.Th'echamber formed Within the trap/'bythetrans'verse wall et abovethe'bott-omof the trap` is pro'- videdl with a fluid pressure':nozzleA 7When' fluid1 under pressure ent'ersthe nozzle chamber Tabelow tlie wall4, the waste in said chamber and inthe chamber of the trap is driven outofl the trap"V structure into and through the waste conduit 6. The' washbasin is indicated' by 8 and its discharge pipe by 9; Pipe 9 entersthetrap at 10.

As there are commonly two Water closets in a car, a Waste conduit- 6afrom a Water closet: not shown is indicated as entrant inf'- to thetemporary storage containerr 11 opposedlyk tothe entrance ot' the wasteconduit* G intothe container'. This container is held suspended from thecar floor abyv braclc ets 12. The nozzle 7- is provided with a controlvalve 1'3 exteriorly of the trap.

A compressed air conduit llconnects with the chamber of the controlvalve and receives air therethrough when the valve is open.

The control valve is connected with the followingoperating mechanism:The upper portion of the water closet bowl has a chamber 16 incommunication with the chamber of its under portion 2. Chamber 16 isprovidedrwith a downwardly opening.;l cover 17 hinged on a rod 1Sprovidedwit'h a rocker arm 19. The upper end ot the rocker arm ispivot'ed' to an end ot'a link 21 the other end ot' which' is pivoted at22 to the downwardly extending' arm 23 ot a bell crank which is' pivotedat' its bend 241 The other armof the bell crank is pivoted` at 25to thebottomot a vertical spindle 26 endwise reciprocalil'e in' a chamberedbearing 2T supported verticallyr inthe water closet bowl structure'.lVithin the chamber of bearing 27, spindle 26 is enclosed by a coilspring: 28 the under end o'l which hears on the bottom wall: ol" thechamber oi" the bearing and the other end of which bears on an abutment29 linedl to the spindle. The upper end ofthe spindle is provided with ahorizontal bracket 30 towhich is lined the upper end of a downwardlyextending rod 3l'. This rod passes through the car i'loor andV i'nto abox` 32 that encloses the trap and the control valve, the waste conduit'G" passing from the trap through an' end wall of the' box 32. The

under end rod 31 is pivot-ed at 33 to an end ofl a link 34 the otherend'ot which is pivoted at 35 to a stationary member. The valve stem 36is' pivoted at 37 midway between its ends to the linl'; 34;.Consequently, when the spindle 26vis pushed' downwardly, it admits waterfrom the usual flush water system not shown into the bowl 1G, swingsopen the cover 17 and opens Athe control valve :tor pasge through itinto the intake end of nozzle ot compressed air or other suitable fluidunder head. In the present embodiment of the invention compressed air isused.

The compressed air reservoir is charged with air under compressionthrough the eduction pipe 38 ot an air pump 39 which is driven by a belt40 'from a pulley 41 on a shalt LQ oi an electric motor M. The motor,air pump and compressed air reservoir are suspended by suitable bracketsfrom the under side oi the car tloor. Motor M is driven from anysuitable. source otl electricity which may be located inan electriclocomotive or may be car storage batteries, through leads m and m1 thatalso connect with an electric switch structure 4?, for automaticallyestablishing electric current from a suitable. source of electricity,not shown, tor operating the motor M. Said electric switch strncture 43(Fig. 5) comprises a piston cylinder to which the reference numeral 43is directly applied. A pipe 43 trom the compressed air reservoir entersthe upper end portion of the piston cylinder which is provided with apiston l? provided on its under side with a downwardly projecting,outwardly flared annulus 79. A coiled spring 791 has its upper endseated in the annulus, abutting` against its upper wall. rlhe under endof the coil spring is seated on a boss 792 the spring extending upwardlyinto the chamber ot the annulus 79 dependent from the cylinder' pistonand integral with its bottom member 791". The flange of the dependentannulus is provided with an electric contact ring insulated trom theflange by insulation 794. Below the piston, the piston chamber containsan upstanding electrode 795 having a downturned upper end for contactwith the contact ring 793. Contact 795 is held in electric connectionwith the lead m1 to a binding stud 796 insulated from the bottom plate797 ot the piston cylinder by insulation 794. Said bottom plate supportsan upstanding electrode 798 havinga downturned upper end in the path ofthe contact ring 793, the electrode 79S being held to the bottom plate797 by a binding stud 799 insulated from the plate. by insulation 794.

Air under compression in reservoir 15 passes through a conduit 44 intothe compressed air nozzle 7 when the control valve 13 is open.

Said compressed air conduit 14 is operatively connected. as shown7 witheach of two partial vacuum forming apparatus through a branch pipe l5for the toilet apparatus shown and through a branch pipe 45a for thetoilet apparatus assumed to be in the other end oil the car.

Then the control valve 13 is open, air trom the nozzle 7 blows throughthe nozzle chamber trap to waste transfer conduit 6 unilsin'iultaneously blows through the conduit 11i and its branch pipe 45into one or both of the partial vacuum forming apparatus. The partialvacuum forming apparatus Vfor the toilet apparatus shown, has a manifold4:6 and the partial vacuum forming apparatus for the toilet apparatusnot shown, has a manifold 4G. Description ot' one partial vacuum formingapparatus will serve for description ot both.

The partial vacuum forming apparatus comprises the manifold 46 into thechamber of which a nozzle 4T depends from the discharge end ot thebranch conduit 45. rlhe under side ot the chambered manifold is providedwith an upwardly flaring tube 4S which extends downwardly into a pipeLlf) entrant in a tank 50 tilled with filtering material rlhe tank 50 isprovided with a discharge tube 5l that passes downwardly through thebottom of the tank, its upper end being in the filtering material andspaced apart from the upper wall of the tank 5() which may be designatedas a muttler and tltering tank. Tank 50 is attached to the side ot avertical liquid seal tank 52, one 'for each container 11 used. The upperend ot' the liquid seal tank 52 is in ported connection at with an upperportion ot the chamber of container 1l. This container has two spacedapart, transverse dependent plates 54 that extend downwardly part way tothe bottom ot' the container into the waste lV. rlhe plates resist unduesurging ot' the waste in the container. Each plate has its upper endperforated at 54a for outflow ol gases.

Compressed air entering the manifolds creates a partial vacuum withintheir chambers and within the upper portion of the chamber of eachliquid seal tank 52 whereby flow of waste from a trap 3, out through awaste transfer conduit 6', into a temporary storage container isinduced. Each liquid seal container 52, contains a liquid seal 55, inits bottom portion and each tank has a transverse dependent plate 56from its top extending` part way downwardly to the bottom of the tankand dipping into the liquid seal. This plate prevents undue surging ofthe liquid seal in the under portion of the seal tank.

The liquid seals and the iiltering material prevent escape of odors andgases from the waste XV, and tank 50 serves as a muiller for the noisethat would otherwise be produced by the rush of air through tube 51 tothe atmosphere.

The filtering material may be mineral wool. Heater' pipes 57 from anysuitable source of heat are shown for chamber of the box 4 and for thechamber of the container l1, the bottom ot which is provided with adischarge port 11a controlled by a stopper device having an operatinghandle 11".

When pressure in the compressed air ill) reservoir 15 falls, the springp1 forces the piston upwards and carries the contact plate p intocontact With the downwardly bent ends ot' the electrodes p5 and p8,whereby a circuit is established through the leads lmJ and m1 for themotor M from any suitable source otl electric current.

Various changes in the form of the above described apparatus may be madeWithout departure from the invention.
